BACKGROUND 1. Technical Field

The present invention relates to carpet installation technology, andmore particularly to a carpet metal sticker for fixing a carpet and acarpet fixing structure.

2. Description of the Related Art

A PVC carpet is a carpet manufactured by using polyvinyl chloride resinmaterial. Specifically, it uses polyvinyl chloride and its copolymerresin as the main raw material which is added fillers, plasticizers,stabilizers, colorants and other auxiliary materials. The polyvinylchloride resin material is formed on a substrate which is a continuousplate by uniform mixing, coating process or pressing/flattening andextrusion process. The PVC carpets can be used instead of pure woolcarpets and chemical fiber carpets, and it have characteristics of softtexture, bright colors, comfortable and durable, easy to clean,non-flammable, self-extinguishing, and moisture resistance. Therefore,they are especially suitable for hotels, shopping malls, stages, etc. Asits good water resistance and slip resistance, the PVC carpets caneffectively prevent the carpet from shifting. Therefore, it isespecially suitable for using in the bathroom. In addition, the PVCcarpet can further pursue the latest fashion and popular decorationafter meeting practical needs since it has unique R&D and productionprocesses.

As a result, the PVC carpets are laid in more and more environments.Recently, the PVC carpets are glued to the ground by glue. It is wellknown that when installing the PVC carpets on the floor, some glue isfirstly sprinkle on the floor and it will not cover the entire floor,but a small amount of glue will be sprayed at intervals. Therefore, whenthe PVC carpets are attached onto the floor and used for a long time,the phenomenon of warping and displacement will occur, which will affectthe use of the PVC carpets.

Therefore, it is necessary to provide a carpet metal sticker which makesit possible to solve the above problem.

DETAILED DESCRIPTION

The present application is illustrated by way of example and not by wayof limitation in the figures of the accompanying drawings. It should benoted that references to “an” or “one” embodiment in this applicationare not necessarily to the same embodiment, and such references mean atleast one.

Referring to FIG. 1 to FIG. 3, a carpet fixing structure is shown inaccordance with an exemplary embodiment of the present invention. Thecarpet fixing structure is used fix at least one a carpet 10, that is tosay, at least one carpet 10 is fixed by at least one carpet metalsticker 20. In the embodiment, for better explaining the structure andworking of the carpet fixing structure, four carpets 10 is fixed by thecarpet fixing structure. The carpet 10 may be a PVC carpet. As wellknown, the carpets 10, such as PVC carpets, include a composite backlayer 11 and a surface layer 12 embedded into the composite back layer11. The composite back layer 11 may be made from polyvinyl chlorideresin material, and so on. The surface layer 12 may be made of Nylon,polyester fiber, and so on. However, the carpets 10 itself should bewell known by a person in the art, and it will not be described indetailed.

The carpet metal sticker 20 includes a base 21, four hook fixing-carpetareas 22 arranged on one side of the base 21, and an adhesive layer 23disposed on the other side of the base 21. The base 21 may has a shapeof round, square, or any other shape, which can be selected according tothe shape of the actual. In the embodiment, the base 21 has a shape ofsquare and only is used for describing the structure of the carpet metalsticker 20. The base 21 can be made of metal or non-metal. When the base21 is made of non-metal, it may be made of plastic, etc. which is easyfor injection molding so as to increase material cost. And, when thebase is made of metal, such as aluminum alloy, etc. it can reduceproduce flow, which may be described in detail as follow. The four hookfixing-carpet areas 22 may have same or different structure and shapewhen the size of the installed carpet 10 is different. In theembodiment, the four hook fixing-carpet areas 22 have same structure andshape, that is to say, the four hook fixing-carpet areas 22 equallydivide the base 21. On a square substrate 21, each of the hookfixing-carpet areas 22 may be square, that is to say, the fourfixing-carpet areas 22 with a square shape combine into the base 21.Each of the hook fixing-carpet areas 22 may be triangle, that is to say,the four hook fixing-carpet areas 22 with a triangle shape combine intothe base 21. Understandably, the hook fixing-carpet areas 22 may be another polygons. In the embodiment, each of the hook fixing-carpet areas22 has a shape of triangle and the triangle is isosceles triangle and abase of the triangle is the side length of the base 21. The four hookfixing-carpet areas 22 intersect at a central point 24, and the base 21further includes a central axis 211 passing through the central point 24and being perpendicular to the plane of the base 21. The central point24 is used as a reference to install the carpet 10. That is to say, whenthe carpet 10 is installed, the corners of the four carpets 10 should belocated on the center point 24 as much as possible so as to insurestability of the carpet 10. The central axis 211 is used as a referenceto set following hook needle 221 provided on the hooking carpet area 22.Each of the hook fixing-carpet areas 22 includes a plurality of hookneedle 221 extending from the base 21 and being made of metal material.An angle between an extension direction of the hook needle 221 and thecentral axis 211 is an acute angle, and the acute angle is between 70degrees and 80 degrees. In the embodiment, the angle between theextension direction of the hook needle 221 and the central axis 211 is75 degrees. The standard for setting the angle is that the hook needle221 can be inserted into the composite back layer 11 of the carpet 10,and not extend out of the composite back layer 11 even if a hammer isuse to hit the carpet 10 toward the carpet metal sticker 20. Therefore,a length of hook needle 221 taken along the extension direction thereofis equal to a thickness of the composite back layer 11. As a result, inany case, the hook needle 221 will not extend out of the composite backlayer 11 and do not enter into the surface layer 12. The hook needle 221may be made of aluminum alloy. Specifically, the hook needle 221 and thebase 21 are integrally formed and the base 21 is made of metal, such asaluminum alloy. Understandably, the hook needle 221 can be punched outfrom the base 21 by stamping. This manufacturing method can reduce theprocess flow and save the manufacturing cost. Moreover, the hook needle221 can also be fixed onto the base 21 by welding, riveting or the like.If the base 21 is made of non-metal material, the plurality of the hookneedle 221 should be welded into the base 21 when the base is molded.Understandably, each of the hook needle 221 should have a tip and thetip can be easily inserted into the composite back layer 11. The tips ofthe hook needles 221 are sharp and have elasticity and hardness, so thatthey can pass cross the composite back layer 11 which is made from PVC,asphalt, or non-woven fabric. The hook needles 221 on each of the hookfixing-carpet areas 22 should be arranged at intervals, so that the hookneedles 221 and the composite backing layer 11 can be coupled to eachother.

The adhesive layer 23 can a suitable double-side tape in the prior art,and the double-side tape can use different glue at the differentapplications. Understandably, if the carpet metal sticker 20 is notused, a release paper layer is adhered to the adhesive layer 23. Whenthe carpet metal sticker 20 is used, the release paper layer should betear off firstly. Then, the side of the base 21 with the adhesive layer23 is adhesived onto a floor, such as cement floor, wooden floor,porcelain tile floor, metal floor and plastic floor, etc., so that themetal carpet sticker 20 can be fixed.

When the carpet 10 is installed, one corner of the carpet 10 is placedonto a corresponding one of the hook fixing-carpet areas 22 and a toolsuch as a hammer can be used to hit the surface layer 12 of the carpet10. As a result, when the carpet 10 is fixed onto the carpet metalsticker 20, the hook needle 221 will be inserted into the composite backlayer 11 and are bent and fallen as shown in FIG. 1. In FIG. 1, the hookneedles 211 have a shape of arc, which is only for illustration, and isnot necessarily arc-shaped in practice. Moreover, since the carpet 10 isstriked by the hammer and the angle between the extension direction ofthe hook needle 221 and the central axis 211 is the acute angle, thehook needles 221 will be contained in the composite back layer 11 and donot extend out from the composite back layer 11.

As described above, in the carpet fixing structure with the carpet metalsticker 20, the carpet metal sticker 20 is divided into the four hookfixing-carpet areas 22, and the four hook fixing-carpet areas 22intersect at a central point 24. Therefore, when the carpet metalstickers 20 are fixed onto the floor and the four corners of the fourcarpet 10 are respectively attached to the four hook fixing-carpet areas22, the four carpet 10 can be aggregated into a whole piece. Since eachof the hook fixing-carpet areas 22 is provided with a plurality of hookneedles 221 and the angle between the extension direction of the hookneedles 221 and the central axis 211 of the base 21 is between 70degrees and 80 degrees, the hook needles 221 can be inserted into thecomposite back layer 11 of the carpet 10 when the carpet 10 is placedonto the hook fixing-carpet areas 22 and is hit by a hammer. Since thelength of the hook needle 221 taken along the extension directionthereof is equal to the thickness of the composite back layer 11, thehook needle will not extend out of the composite back layer 11.Moreover, the hook needle 221 will be bent and fallen during the carpet10 is hit. As a result, the hook needle can buckle the composite backlayer 11 of the carpet 10 so as to fix the carpet 10 onto the carpetmetal sticker 20 and avoid the phenomenon of warping and displacement ofthe carpet 10.
